I had the same problem with my Epson scanner when updating my laptop to Win XP, you will have to go to Canon's web-site and look for their DOWNLOADS & PATCH page. Look for a new TWAIN DRIVER download for your application ( scanner model ) I hope this takes care of your problem, Good Luck!
Im trying to install my canon scanner but firstly plug and play wont recognise it exists and ive worked out that when i try to install the driver it says i need to install a twain driver... can any one please help me !? im using windowns xp the scanner previously worked on the computer b4 i reformatted
anyhelp would be great
thanks
